Google is a search engine. Libraries subscribe to Databases. Although you use both to search, they are very different things.
Start your search with these popular databases:
General database of academic journals in the sciences and humanities. Includes full text scholarly / peer-reviewed articles.
Now called Gale eBooks.
Multidisciplinary database of full text encyclopedias and reference sources for research and ready reference. Enables one search that covers all sources. Subjects include arts, sciences, medicine, and the humanities.
